虹膜缝线固定折叠人工晶状体的临床效果

摘要

Objective To evaluate the clinical effects of iris-fixated foldable lens.Methods 62 patients (63 eyes) who had insufficient posterior capsular support for intraocular lens had been divided into two groups randomly,group A underwent iris-fixated foldable lens implant,group B underwent scleral-fixated foldable lens implant,3 months after operation,visual acuity and refractive status were compared; the first 4 weeks postoperatively,dyndall effect was observed every week.Results 3 months after operation,the UCVA was better in group A (0.43 ± 0.19)than in group B (0.35 ±0.18),but the BCVA had no difference between the two groups; The postoperative UCVA:12 of 31 eyes (38.7％)in group A were better than preoperative BCVA,and the percentage in group B was 12.5％ (4/32),however,9 of 31 eyes (29％) in group A and 18 of 32 eyes (56.3％) in group B were worse than preoperative BCVA; postoperatively,the sphere in group A was minus (-0.47D ±0.58D),and that in group B was plus (0.50D ±0.43D),the cylinder in group A (0.84D ±0.53D) was smaller than in group B (1.23D ±0.70D),the difference was statistical significant,but the corneal astigmatism had no difference between the two groups; there were less complications in group A than in group B.Conclusion In short term,compared with group B,the visual results and refractive effects in group A were better.%目的 评价虹膜缝线固定折叠人工晶状体的临床效果.方法 随机数字法将无晶状体眼62例(63眼)分成A、B两组.A组行虹膜缝线固定植入折叠人工晶状体,B组行巩膜缝线固定折叠人工晶状体,术后3个月比较两组视力和屈光状态.术后4周内,每周观察前房闪光.结果 术后3个月,A组裸眼视力为(0.43±0.19)优于B组的(0.35±0.18),P ＜0.05,差异有统计学意义；最佳矫正视力(BCVA)两组差异无统计学意义；术后裸眼视力:A组有38.7％(12/31)高于术前最佳矫正视力(BCVA),B组有12.5％ (4/32)高于术前最佳矫正视力BCVA；A组有29％ (9/31)较术前最佳矫正视力降低,B组有56.3％(18/32)较术前最佳矫正视力降低.显然验光球镜,A组成近视化趋势(-0.47±0.58)D,B组成远视化趋势(0.50±0.43)D；显然验光柱镜,A组(0.84 ±0.53)D小于B组(1.23 ±0.70)D,差异有统计学意义；角膜散光,两组差异无统计学意义；A组与B组相比,有较少并发症发生.结论 短期观察,虹膜缝线固定折叠人工晶状体视力效果、屈光效果优于巩膜固定折叠人工晶状体.
